Recruiting studies
- NCT04469439Recruiting
Sinus surgery in adults with cystic fibrosis
This study looks at how endoscopic sinus surgery affects people with cystic fibrosis who have ongoing sinus problems even after medical treatments. It may help doctors understand whether surgery plus ongoing care improves symptoms and quality of life.
Los Angeles, CaliforniaAges 18–99 - NCT05061329Recruiting
Learn how the nose’s microbes relate to health and disease
This study explores the tiny living organisms (microbes) in your nose and how they may be linked to health problems. It may help researchers better understand disease triggers and potential new prevention or treatment ideas.
Holstebro, Central JutlandAges 18 years+ - NCT05708300Recruiting
Testing how mepolizumab works for people with nasal polyps
This study looks at blood and other measures (biomarkers) to understand how well mepolizumab helps people with nasal polyps, with or without asthma. It aims to find response clues that could help personalize treatment in the future.
Thessaloniki, ExochiAges 18 years+ - NCT05902325RecruitingPhase 4
Testing who benefits most from mepolizumab for nasal polyps
This study looks at why some people with severe chronic nasal polyps respond better to mepolizumab. It may help doctors predict who will benefit from the medicine, and who may need a different plan.
Montreal, QuebecAges 18 years+ - NCT06191640Recruiting
Study of sinus disease in young children with cystic fibrosis
This study looks at sinus problems in young children with cystic fibrosis. One group of children starts a new medicine called a highly effective modulator (like Trikafta), and the other group does not take this medicine. The goal is to see how the medicine affects sinus health over time.
Aurora, ColoradoAges 2–8 - NCT06892704Recruiting
Dupilumab smell restoration study for CRSwNP
This study tests if the medication dupilumab can improve smell loss in people with chronic sinusitis and nasal polyps. Researchers will check if blocking in the nose and electrical signals in the brain can predict who will benefit.
Chicago, IllinoisAges 18–65 - NCT06996951RecruitingPhase 3
Sinus treatments in cystic fibrosis with modern modulator therapy
This study looks at how different sinus treatments affect people with cystic fibrosis who are taking modern modulator therapy. It aims to understand which rinses work best for chronic sinus problems.
Indianapolis, IndianaAges 18 years+ - NCT07681973Recruiting
Smell training for loss of smell in sinus patients
This study tests whether smell training can improve your sense of smell and affect your immune system. It is for people with chronic sinus inflammation and nasal polyps who have lost their sense of smell.
Cleveland, OhioAges 18 years+ - NCT07262450Recruiting
Seawater spray for stuffy nose and sinus symptoms
This trial tests whether a seawater nasal spray can relieve nasal congestion, runny nose, and other sinus symptoms in people with colds, allergies, or after nose surgery. You will use the spray as directed and answer online questionnaires for up to 3 months.
BordeauxAges 2 weeks+ - NCT07299474Recruiting
Lavender scent for anxiety and pain during awake ENT procedures
This study tests whether smelling lavender essential oil during an awake ear, nose, or throat procedure can help reduce anxiety and pain. If you qualify, you may receive the lavender scent during your procedure and report how you feel.
Los Angeles, CaliforniaAges 18 years+ - NCT05531630Enrolling by invitation
Xylitol versus saline rinses for sinus symptoms in adults with CF
This study compares two kinds of nasal rinse packets—xylitol versus plain saline—to see which better reduces sinus symptoms. It may help adults with cystic fibrosis and long-term sinus inflammation feel better with routine, at-home nasal care.
LeuvenAges 18 years+ - NCT06567821RecruitingPhase 2/Phase 3
Using navigation to improve balloon sinus surgery accuracy
This trial tests whether using a navigation system during balloon sinus surgery makes the procedure more accurate for people with chronic sinusitis. It may help improve outcomes for those who have not had sinus surgery before.
Los Angeles, CaliforniaAges 18 years+ - NCT04645511Recruiting
Balloon treatment for long-term or repeat maxillary sinusitis
This study tests whether balloon sinuplasty works better or more efficiently for people with long-lasting or repeatedly returning inflammation in the maxillary sinuses (side sinuses near your cheeks). It focuses on people who did not improve with the usual nose spray (topical steroid) or who meet specific “recurrent” episode patterns.

Common questions
- Are there clinical trials for chronic rhinosinusitis?
- Yes. Clin2 currently lists 61 recruiting chronic rhinosinusitis studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a chronic rhinosinusitis trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a chronic rhinosinusitis trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
